Options

A. Man
B. Insects
C. Sycon
D. Reptiles

Explanation

**Step-by-Step Solution:**

1. **Understanding Peri Blastula**: Peri Blastula is a type of embryonic structure that forms during the early stages of development in certain organisms. It is a specific type of Blastula.

2. **Identifying Organisms with Peri Blastula**: According to the information provided, Peri Blastula is found in various organisms, including humans (Man), insects, reptiles, and others. However, it is particularly noted for being associated with organisms that have Centro-Lacithal-Eggs.

3. **Defining Centro-Lacithal-Eggs**: Centro-Lacithal-Eggs are characterized by having yolk concentrated in the center of the egg. This type of egg is commonly found in insects.

4. **Formation of Morula and Blastula**: The process of cleavage leads to the formation of a Morula, which is an 8 to 16 celled structure. Further cleavage results in the formation of a Blastula, which can consist of 32 to 125 cells.

5. **Conclusion**: Based on the characteristics of Peri Blastula and its association with Centro-Lacithal-Eggs, the organisms where Peri Blastula is found include insects. Therefore, the correct answer to the question is that Peri Blastula is found in insects.

**Final Answer**: Peri Blastula is found in insects.
